Latest Patents

One of Trung H Lam's latest patents is a low noise amplifier with a fixed loss bypass. This innovative design integrates a selectable bypass signal path into the same integrated circuit as the amplifier components. In normal operation, an integrated mode switch applies an appropriate biasing signal to the LNA transistors, allowing them to amplify an input signal and produce an amplified output signal. In attenuation mode, activated to handle large input signals, the LNA transistors are switched off, and the input signal is attenuated by a voltage divider, providing an attenuated output on a signal path that bypasses the LNA amplifier. An attenuation switching signal operates the mode switch in the LNA and selects between the normal and bypass outputs for further amplification downstream.

Another significant patent by Lam is the compact lumped element ring balun layout. This design features elements patterned on a monolithic substrate in a compact configuration. The balun includes four inductors and a plurality of capacitors electrically coupled to provide RF output signals that are 180° out of phase with each other. The inductors are symmetrically disposed in a rectangular area on the substrate, with a first pair positioned at one end and a second pair at the opposite end. All capacitors are formed on the substrate in a central circuit area between the two pairs of inductors, ensuring efficient signal processing.
